Best Ten Smartphones for
Battery Efficiency 2021 - 2023

Smartphone power efficiency refers to the ability of a smartphone to maximise its performance while minimising power consumption. It is a crucial aspect for smartphone users as it directly impacts battery life and overall device usage

ViserMark introduced the first Battery Efficiency Label in the world to show the battery energy efficiency of the device. It is calculated using Battery Life and Battery Capacity.

This is expressed in “Leaves" and reflects a rating between 1 being the least and 5 being the most power-efficient.

The smartphone power efficiency can vary among different smartphone models and manufacturers.

The hardware components of a smartphone, such as the processor (CPU), graphics processing unit (GPU), and modem, play a significant role in power efficiency. Advanced chipsets and processors are designed to deliver high performance while consuming minimal power. Manufacturers often optimise the hardware to strike a balance between performance and energy efficiency.

Also, the operating system (OS) and software play a crucial role in power efficiency. Smartphone manufacturers invest in optimising the software to minimise power consumption by managing background processes, app management, and resource allocation. Regular software updates often include power-saving optimisations to improve efficiency.
